Abstract: A linear drive apparatus (10) for moving a carton (175) in a packaging machine from a first position to a second position is set forth. A first drive belt (115) is connected to a drive roller (75) and disposed about the drive roller (75) in a clockwise direction at a first end thereof while a second end of the first drive belt (115) is connected to a first position of an engagement assembly (15). A second drive belt (95) is connected to the drive roller (75) and disposed about the drive roller (75) in a counter-clockwise direction at a first end thereof while a second end of the second drive belt (59) is connected to a second portion of the engagement assembly (15) opposite the first portion of the engagement assembly (15). The rotation of a drive shaft (80) in a clockwise direction causes linear movement of the engagement assembly (15) in a first direction along the guide rods (50) and the rotation of the drive shaft (80) in a counter-clockwise direction causes linear movement of the engagement assembly (15) in a second direction opposite the first direction.

Abstract: L'invention concerne un procédé de fabrication de tuyaux ou de corps moulés tubulaires en béton au polymère. Ledit procédé consiste à introduire une masse de remplissage minérale dans la cavité (6) d'un dispositif de moulage (1) vertical et comportant un noyau (3) avec différentes zones de traitement mobiles dans le sens axial ainsi qu'un surmoule (4) fixe entourant à distance le noyau. Le procédé consiste ensuite à secouer la masse de remplissage minérale et à la faire durcir. La masse minérale commence à être secouée dans la cavité (6) au début du processus de fabrication, pendant ou après le remplissage d'une partie de la cavité (6) avec la masse minérale. Lorsque la colonne de matière constituée de masse de remplissage minérale s'accroît dans la cavité (6) et lorsque la masse minérale a déjà commencé à être secouée, un apport de chaleur est effectué dans une zone de chauffage située en aval de la zone où la masse est secouée. Lorsque la masse de remplissage minérale a commencé à durcir dans la partie inférieure de la cavité (6), l'ensemble de la colonne de matière se trouvant dans la cavité (6) est déplacé vers le bas et chaque partie de la colonne en cours de durcissement est évacuée de la cavité (6). Un remplissage continu ou intermittent de la cavité (6) avec la masse minérale permet de compléter la colonne de matière et de faire passer en continu la masse minérale complétée à travers la zone où elle est secouée et à travers la zone de chauffage.

Title: Apparatus and methods for multiple fluid infusion
Inventor: SANCOFF GREGORY E
IPC: A61J1/00
Filed: 1995-09-15
Abstract: We disclose apparatus and methods for delivering for patient infusion or other use two or more fluids either sequentially or simultaneously. The apparatus (100) has a fluid delivery compartment (101) containing a first infusion fluid (103), a flexible membrane (104), and an openable bag (150) containing a second infusion fluid (152). An attached gas reaction compartment (121) contains chemical reactants (123, 134) which, when combined, react to evolve gas (122). The gas (122) expands a gas expansion chamber (102) causing the membrane (104) to move into the fluid delivery compartment (101), displacing the first infusion fluid (103). The membrane (104) eventually contacts and compresses the openable bag (150). Pressure from the membrane (104) causes the bag (150) to open and discharge its contents out of the infusion device (100).

Title: Method of adjusting tension applied to sheet, and device for the same
Inventor: YUYAMA SHOJI
IPC: B65H75/18
Filed: 1997-08-29
Abstract: It is desired to prevent disalignment of the edges of a folded sheet by smoothly feeding the sheet while keeping tension fluctuactions to a minimum when the sheet is unwound from a paper roll set in a paper feed unit to a packaging unit even though the paper roll diameter decreases gradually as the sheet is unwound.  A sheet length measuring sensor or rotary encoder is provided in the paper feed path through which the packaging sheet unwound from the paper roll is fed toward the packaging unit.  An angle sensor is provided which comprises Hall element sensors provide on a support shaft and magnets provided on a core pipe of the paper roll.  Any change is the signals from one of these sensors relative to the signal from the other sensor is used to calculate the paper roll winding length, and the sheet tension is adjusted to an optimum, constant level by controlling the sheet braking force stepwise according to the roll diameter measured by the sensors.

Abstract: A tank for a pad-mounted transformer comprises: (i) a casing that is C-shaped in cross section and comprises spaced-apart parallel arms of sheet form and a rounded back wall connecting the arms and (ii) a combined front wall and bottom that is of a generally-L-shaped cross-section when viewed from a first reference plane extending parallel to the arms. The front wall is spaced from the back wall to provide an interior space between these walls. The bottom when viewed from a second reference plane perpendicular to the first reference plane, has a rounded periphery that nests within the C-shaped casing. The combined front wall and bottom has a flange that extends around its periphery, abuts the interior surface of the C-shaped casing, and projects away from said interior space. The flange is roll seam welded to the casing by utilizing a welding machine comprising a pair of roller electrodes between whichwelding current passed as the roller electrodes move relative to the parts being welded. This welding operation is performed by causing the roller electrodes to roll along the length of the flange during the welding operation.

Abstract: ABSTRACT             In a mobile satellite system, a mobile communication system includes a system for managing a mobile satellite system and a mobile communication system responsively connected thereto for registration. The system includes a management system (CMIS) requesting registration of the mobile communication system in the satellite communication system and creating a CMIS record responsive thereto, and a protocol conversion system (DM). The DM performs the functions of receiving and converting the CMIS record to a common record, and transmitting the registration request to the central controller of the CGS. The DM also receives a registration acknowledgement from the central controller indicating that the registration request was completed by the CGS, converts the registration acknowledgement into the common record, and transmits the registration acknowledgement to the CMIS. The DM also receives a ready indication for a commissioning status message from the central controller, transmits the status change response to the CMIS indicating a ready for commissioning status. The DM receives and transmits to the CMIS an operational/failed status message indicating whether the mobile communication system was successfully commissioned.

Title: Method and apparatus for non-intrusive measurement of round trip delay in communications networks
Inventor: HASSELKUS JOHN E
IPC: H04L12/24
Filed: 1996-04-17
Abstract: Measurement of round-trip delay or travel time in a communications network during in-service operation is accomplished by use of two probes (12, 13), situated at respective points of interest along the communication network, and a processor. The probes (12, 13) receive identifiable data patterns normally transmitted over the communications network and generate a time stamp when each pattern arrives at or leaves the respective point. Each probe further generates a pattern identifier based on the data in the pattern and stores the identifier and time stamp as a pair in a buffer internal to each probe. Once the internal buffer contents exceed a predetermined amount of data, the processor receives the data from the buffers to locate the departure and arrival time stamps of each pattern traveling between the probe points.
